6m Divided by 2.7 Seconds 
6/2.7=<span>2.22222222222
 2.22222222 Meters per second is end velocity
the change in velocity is Start velocity (0m/s) - end velocity (2.222222222m/s)
So the Change in velocity is 2.222222222m/s
To find acceleration it is Change in velocity (2.2222222m/s)/Time (2.7m/s)
2.222222222222/2.7=</span><span>0.82304526749
acceleration=</span><span>0.82304526749 Meters per second Squared
This also would make sense as we already know acceleration is less on the moon.
Answer=</span>0.82304526749m/s ²<span> </span>

Bogdan [553]
The ratio 11:4 means that the total number of spaces is a multiple of 15 parts, this multiple is what value is assigned to each part.

450/15=30  so each part is equal to 30 spaces

Full sized car spaces are 11*30=330 spaces

Compact car spaces are 4*30=120 spaces.

Answer:

Carla lives 16 miles from the Library.

The mistake is drawng the diagram incorrectly and using the miles given in the wrong places. The <u>student's</u> diagram has Yuri in a place that's Southwest of the Library in the diagram given

Step-by-step explanation:

If Yuri lives 24 miles SOUTH of the library, the "b" side of the triangle should be 24, with the Library at the top and Yuri at the bottom left, which is the west end of the base. The base "a" of the triangle should extend 10 to the right (East in compas directions) forming the right angle. Carla lives at the sharp southeast corner of the triangle, and the Hypotenuse "c"  from her house to the Library is the distance we have to figure.

c² =a² + b²

c² = 10² + 24²

c² = 100 + 576

c² = 676

√c² = √676

c = 26       Carla lives 26 miles from the Library.
